16. Applications and Implications

This week’s assignment is

Propose a final project masterpiece that integrates the range of units covered.

Your project should incorporate:

2D and 3D design DONE
Additive and subtractive fabrication processes DONE
Electronics design and production DONE
Microcontroller interfacing and programming DONE
System integration and packaging. DONE

Where possible, you should make rather than buy the parts of your project. Projects can be separate or joint, but need to show individual mastery of the skills, and be independently operable.

So my final project is the digital anemometer. The idea is that the anemometer should measure speed of wind send it through RF to the PC.

WHAT IT WILL DO

It will measure speed of wind and send data each second to the PC.

WHO HAS DONE WHAT BEFOREHAND

There are lots of examples of digital anemometers, but the difference is that it should work with the set of anemometers.

WHAT WILL YOU DESIGN

I will design PCB, wings to measures speed, a packaging box from acrylic and an interface software to connect it with PC.

WHAT MATERIALS AND COMPONENTS WILL BE USED

  1. 9V battery
  2. ATMEGA328p Microcontroller
  3. NRF radio transceiver
  4. power switch
  5. 3D printed wings
  6. few resistors and capacitors

WHERE WILL THEY COME FROM

From Fablab repository.

HOW MUCH WILL THEY COST

Approximately 30 USD.

WHAT PARTS AND SYSTEMS WILL BE MADE

The main PCB, package box, and wings.

WHAT PROCESSES WILL BE USED

  1. 3D printing(wings)
  2. 2D milling(PCB)
  3. Laser cutting (Box)

WHAT QUESTIONS NEED TO BE ANSWERED

  1. The accuracy of measurement.
  2. The distance of radio communication.
  3. Tolerance under strong wind.
  4. Is there an opportunity to use more sensors with the same MCU?

HOW WILL IT BE EVALUATED

The project can be called successful if all the designed parts matching each other Device measures the speed and sends through rf and PC receive data It is able to measure the speed of wind from 0 to 70 km/h. PC software stores data in log file.
